Stenger test

The Stenger test is a test when a patient is suspected of feigning/faking a hearing loss and is based on
the auditory phenomenon, "The Stenger Principle", that states that only the louder of two similar tones
presented to both ears at the same time will be perceived. As a general rule it has been recommended to
perform the Stenger test in case of unilateral hearing losses or significant asymmetries.
Please refer to the Tone Test section above for key function descriptions for Function Keys (7), (10), (11),
(12), (13), (14).
